Akande had announced the visit Tuesday night and that Osinbajo would return immediately after. A Federal Executive Council Meeting takes place every Wednesday in Abuja.

“Osinbajo meeting with President Buhari in London today, and returning to Abuja immediately afterwards,” the vice president’s spokesman, Laolu Akande, said in a Twitter message posted earlier on Tuesday. No details were given.

President Buhari, 74, left Nigeria the night of 7 May after welcoming a group of 82 Chibok schoolgirls released by the militant group Boko Haram.

It was President Buhari’s second medical visit to Britain this year. The first began in January and lasted nearly two months.
